Well, you might need SB, although Castillo should give you plenty. I think you'll likely miss some HR also, since you don't have any of the potential 40 HR guys like Pujols, A-Rod, Sexson, Thome, Guerrero, Bonds, Sosa...

Your pitching is pretty good, although I don't understand why you have Timlin on your roster. E. Jackson is likely heading back to the minors, so you might want to find him a substitute. Try to grab a potential closer Riske, Lopez, Graves, Chacon...
